JOSM Saving blank files / Converting Shapefiles to OSM

Hello,

I am using Blender to create 3D City scenes using OSM data for an animation project. I am trying to convert shape files to OSM format so I can import them into Blender. My shape files are historic data so I create 3D historical scenes.

I’ve been trying to use JOSM to convert my shape vector files to OSM data so I can import them into Blender. I can convert to OSM using the Open Data Plugin, I can save and open them again in JOSM fine. But when I try and open my converted OSM file using QGIS or Blender the file is blank.

What am I doing wrong? Is there a better way to convert Shape to OSM?

Try ogr2osm http://wiki.openstreetmap.org/wiki/Ogr2osm

see http://wiki.openstreetmap.org/wiki/Shapefiles for more possibilities.
